But the smile was soon wiped off Foxy's face when jurors were shown graphic pictures of British student Meredith Kercher's dead body.

American Knox, 21, did not look at the images as they were shown on a video screen. Instead, she kept her head down and covered it with her arms.

Her co-accused Raffaele Sollecito, 25, glanced at them sporadically. During a break in the hearing in Perugia, Italy, Knox's mother Edda Mellas said: "The images upset her too much." Pathologist Luca Lalli told the court that Meredith's body showed evidence of "sexual activity" but said he "could not prove if there had been violence".
